I had a cad drafter draw plans what files does he owe me autocad 2011

I posted a project on Elance to have a custom cabinet design drawn in AutoCad 2011. The cabinet panel dimensions and technical drawings were created. 2D and 3D renders. I want to make sure I get the proper AutoCad 2011 original files from the designer. I want to know what files and format type he should supply me with so I can give them to other AutoCad 2011 designers to be able to make changes if necessary. What file extensions, etc?
